Abstract :
In this paper, the multi-voltage control strategy of single-phase inverters is proposed for lower total harmonic distortion (THD) of the output voltage. 3rd, 5th and 7th harmonics of the output voltage are extracted and controlled in their own synchronous rotating reference frames. Therefore the zero steady-state error can be achieved. It is verified that the pointed out control scheme gives approximately sinusoidal voltage of the 30kVA inverter supplying nonlinear load.
